Io all whom it may concern:

Be it known that 1, JOHN Sri'atrnonr, a citizen of the United States,and resident of New York city, borough of h lanhattan, in

the county of New York and State of New York, have invented certain newand useful be more efficiently generated and distributed,

the construction of the armature will be facihtated, and its costreduced.

The invention comprises novel details of I improvement and combinationsof parts that will he more fully hereinafter set forth and then pointedout in the claims.

Reference is to be had to the accompanying drawings forming part hereof,wherein, Figure 1 is a partly sectional sideview of an armatureembodying my improvements; Fig. 2 is an end view partly in section; Fig.3' is an end view of the armature, parts bein removed; Fig. 4 is adetail perspective View of one of the armature heads; Fig. 5 15. adetail perspective view of the nonmagnetic shell ;'Fig. 6 is a detailperspective view of an insulating piece of the armature, and Fig. 7 is aface view of one of the laminated plates. I

Upon a suitable shaft 1 are mounted a series of metal plates 2 which areshown having curved end portions 2* and centrally located oppositelydisposed projections 2", providing s aces 3 in which the windings ofsuitably insulated Wire 4 are located.

At- 5 are heads at the ends of the anma ture secured on 'opposite'sidesof the laminated plates 2, as by screws or bolts 6 passing through saidheads and plates. My improvements comprise a new form of 45 the lieadsfor the armature in that the curved end portions '5 are madeintegralwith the ing out and parts to shape from a piece drawing saidoft-suitable metal, whereby the general con- .struction of said heads isimproved. and

strengthened, the cost of producing such and the efficiencyv of the sameis increased The pross members 5" of said heads are shown providedwithpro V jections 5 on opposite sides which correspond to and are in linewith the projections 2 of plates 2, and shaft 1 passes throughthecentral openings in heads'o.

At 7 are non-magnetic'plates having cen tral-bores to fit upon shaft 1and located against the corresponding faces of heads 5. Said plates maybe made of brass and have their ends turned outwardly at 7? to fitwithin or adjacent the inwardly curved edges of the enc members 5 ofheads 5, and the parts 7 arebent up from the sheets of metal 7 tocorrespond and aline with the parts 7, providing intermediate spacesfor'tlhe windings 4, the parts 7 being shown struck up from rojectingparts. 7 which correspond with rd lie against the parts 5 of heads 5.

At 8 are insulating sheets fitted upon'the laminated plates 2 betweenthe parts 7 7 the windings 4 coming between said plates S, the parts 7*,7", forming walls against :which the insulating plates 8 bear and thusforming channels for the windings 4. On one of the heads 5 is placed aband or ring 9 of non-magnetic metal, such as brass,

for which purpose the end of part 5 of head I 5 is shown reduced at 5 toreceive band 9. A suitable brush or the like 10 bears against band 9 tocollect the current from the same.

WVindi-ngs 4 on opposite sides of the armature are connected together,as at 4, and one end of said winding is grounded on one of the heads 5,and the other end of the winding is shown connected with a pin 11passing acrossshaft 1 and insulated there- -from by insulation 12, pin11 being secured in a pin 13 passing through a bore of insulationc14enteringthe bore in one end of shaft 1, said insulation 14 being shownprovided with a head 14 at one .end bearing against the end of theshaft, the head 13 of pin 13 hearing against head 14", whereby currentmay be ta on from head 13*.by any suitable .brush or contact. By meansof my improvements the parts may be readily assembled and taken apart,windings, the general elliciency of the mature is increased, thearmature may .be run at relatiely high speed without injury. It willbe.und erstood that the armature may rotate in any magnetic field, asbe;

current is more effectively confined m illustrate.
